Understanding the concept of “Normal Distribution” is important in understanding the status of pedigree regulations in the United States pharmaceutical supply chain. The term itself didn’t exist back in the late 1980’s when the federal Prescription Drug Marketing Act (PDMA) pedigree provisions were originally enacted by Congress but the concept is built into that law as the “Authorized Distributor of Record” (ADR) concept. When states began enacting their own pedigree legislation back in the early 2000’s, the term “normal distribution channel” was defined to describe the path of drugs when they move through the most common–or “normal”–sequence of supply chain owners. It’s a concept that is explicitly defined in most state pedigree legislation.

When a pedigree law is a “normal distribution” law, it generally means that pedigrees are not needed for any shipment or change of ownership where the drugs do not leave this common/typical/normal path as defined in the law. But as soon as a change of ownership or custody occurs where the drug leaves this “normal” path, a pedigree is then necessary.

“…[C]ommencing on July 1, 2016, a wholesaler or repackager may not sell, trade, or transfer a [prescription] drug at wholesale without providing a pedigree.

…[C]ommencing on July 1, 2016, a wholesaler or repackager may not acquire a [prescription] drug without receiving a pedigree.

…[C]ommencing on July 1, 2017, a pharmacy may not sell, trade, or transfer a [prescription] drug at wholesale without providing a pedigree.

…[C]ommencing on July 1, 2017, a pharmacy may not acquire a [prescription] drug without receiving a pedigree.”

With these words the State of California introduced a significant change to the way the pharmaceutical supply chain works (see section 4163 of the California Business and Professions Code) and has written a new page in the history of commerce. It brings pharmaceutical commerce fully into the computer age. Adam Smith would not recognize it. Today, and up to the effective dates of these provisions, the value of a legitimate pharmaceutical in the legitimate U.S. supply chain is determined by the physical condition of the product and its package. After July 1, 2016, the value of a legitimate pharmaceutical in the supply chain in California will be determined by the combination of the physical condition of the product and its package, and the sellers ability to provide the buyer with an electronic pedigree.

The intended effect of this new regulatory requirement is to place a significant roadblock in front of counterfeiters, diverters and others who would try to scam patients and the legitimate participants in the supply chain. This is a noble cause. By requiring sellers to provide buyers with a pedigree at each change in ownership in the supply chain, illegitimate parties will find it very hard to inject illegitimate drugs without exposing their actions and, at the same time, creating evidence that can be used against them in their own prosecution. By providing a pedigree at each change in ownership, supply chain buyers will be able to check the authenticity of the full supply chain transaction history provided by the seller, maximizing the likelihood that any suspicious activity would be detected long before a patient would receive the drugs.

In an essay published in April, I explained my theory that “RFID is DEAD…at Unit-level in Pharma”, which, if true, would mean that most drugs in the U.S. supply chain would be serialized by manufacturers with 2D barcodes by 2015 for California. In my last essay, “Inference in the Pharmaceutical Supply Chain”, I carried that theory one step further by showing how the widespread reliance on 2D barcodes to serialize at the unit level would lead directly to the widespread use of the practice of inference in the supply chain. This would be out of necessity since the unit-level serial numbers would not be readable without opening their containers, something that can’t happen because it is so inefficient that it would cripple the supply chain. So let me say it this way, the widespread use of 2D barcodes for unit-level serialization will necessitate the widespread reliance on inference. The former leads to the latter just like excessive sunshine leads to sunburn.

But the projections of widespread reliance on inference lead directly to a new concern. Let me explain. Successful use of inference for determining the contents of cases is totally dependent on the accuracy of the aggregation information established and provided by the manufacturer, or whoever packed them. If a packer uses a casepacking process that is incapable of yielding highly accurate aggregation information, inference will not work well.
